Hi Dave, welcome to the forum :slight_smile:

I am sorry you had to spend so much time to fix the problem ! As you are no longer using SecureLine, you can remove it as well :

  1. Start - Control Panel - Add/Remove Programs - Avast! - Change.
  2. Change.
  3. Uncheck SecureLine.
  4. Continue.
  5. Reboot.

Greetz, Red.
